UNITED STATES PATENT JOHN V. FOSTER, OF WESTFIELD, MASSAOHUSET"S, ASSIGNOR TO THE I FOSTER MACHINE COMPANY, OF SAME PLACE.

STOP-MOTION FOR SPOOLING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 499,665, dated June 13, 1893.

Application filed August 6, 1892- Serial No. 442,832. (No model.)

To all whom it may concern: 1

Be it known that I, JOHN 'W. FOSTER, 0 WVestfield, county of I-Iampden, State of Massachusetts,have invented an Improvement in Stop-Motions for Spoofing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts. 5

This invention has for its object to impro Ye and simplify stop motion devices used in spooling machines.

United States Patent No. 404,831, granted to me June 11, 1889, shows a form of stop motion wherein a tipping lever under the control of a drop wire is, when acted upon by a drop wire, moved longitudinally to effect the stopping of that drum which rotated the spool to which the said yarn was being supplied. In said patent the tipping lever was carried by a sliding bolt, and with said bolt there was combined devices for unlocking a brake to act against the driving drum.

In the present invention, the tipping lever, when acted upon by the ratchet wheel, a yarn having been broken, acts on the brake lever and causes it to act as a brake against the driving drum, preferably in the form of a shell roll such as common to United States Patent No. 459,039, and instantly stop the rotation of that driving drum or shell roll.

Figure 1, in vertical section and elevation shows a suflicient portion of a spooling machine with my improvements added to enable my invention to be understood. Fig. 2, is a detail showing the brake or lifting lever. Fig. 3, shows the tipping lever and its stand detached from the machine; and Fig. 4, a detail of the brake or lifting lever.

A represents a portion of the frame-work of a spooling machine; A a cross rail, it, as herein shown, supporting a stand A having suitable bearings for an intermediate roll A said stand also having guide wires 2 upon which slides a suitable traverse guide 77. shown chiefly by dotted lines in Fig. 1, said traverse guide having suitable eye or eyes for the reception of the yarn y to be wound upon a suitable receiver a, a tube or cone, placed upon a roller having its journals held in suitable hearings or notches of a yoke a pivoted at M, said yoke having preferably cooperating with it a suitable friction device, as a to aid in keeping it in the position in which it is put by the accumulating mass of yarn a being wound upon the yarn receiver. The rail or other suitable part of the framework has suitable bearings, not shown, for the shaft 6, having as represented fast to it disks e surrounded by a driving drum h, said I driving drum in practice, having, as provided forin United States PatentNo.459,039,acrossing groove to receive the foot of a stud extended from the traverse device 7L3 into said groove, the groove causing the traverse device to lay the yarn from end to end of the receiver, of whatever form.

As provided for in the patent last referred to, the driving drum, represented as a shell roll, hangs by its weight upon the disk 6 and is rotated thereby, but the rotation of the roll may be stopped instantly by simply lifting it so as to break contact between it and the disk 6. Preferably the roll A common to the said patent, will be interposed between the shell roll and the mass of yarn beingwound.

Depending from the cross-bar A is a stand having a ratchet wheel 33, said ratchet wheel being common to United States Patent No. 404,831, granted to me June 11, 1889, it in practice-being fast on the shaft 3e which may be rotated, as provided for in the said patent, or in any othersuitable manner. Depending also from the said cross-bar is astand 3, upon which is pivoted at 4 a leg 5, said leg having a suitable pivot 6 upon which is mounted a tipping lever 32. The outer end of the lever 32 has, as represented, a projection '7 which may be a rod, see Fig. 3, and immediately above the outer end of the tipping lever is arranged a drop wire I) which hangs on the yarn coming from a suitable spool B over suitable friction rollers b, b 12 of any desired number. The frame-work has another stand 0 which supports a fulcrum O for a suitable brake or lifting lever 0 said lever as herein represented, having a notch 8 and an incline 9, the latter shown by dotted lines Fig. 1, and a stop 10. The inner end of the tipping lever is somewhat heavier than its outer end, so that the said end normally rests against the stop 10, as represented by full lines in Fig. 1.

When the yarn is unbroken the drop wire is kept up, as shown by full lines in Fig. 1, but should the yarn break, the drop wire 1) drops, strikes the outer end of the tipping lever, turning it into its dotted line position, so that the continuously rotating ratchet wheel 33 strikes the inner end of the tipping lever and moves it, viewing Fig. 1, to the right, causing the lower end of the leg 5 to ride along the incline 9, thus turning the brake or lifting lever 0 about its fulcrum G, causing the inner end of said lever, faced preferably with india-rubber or other pad as d, to act against the driving drum or shell and lift the same or check its rotation. The lower end of the leg 5 after traveling up to the incline 9 enters the notch 8, and it thereafterv acts as a locking device for the brake or lifting lever. The yarn having been mended between the friction rod 12 and the traverse guide, there being buta very. short stretch of yarn between i the two, and the drop wire having been again lifted and strung upon the yarn", the operatorv to start the machine will simply push down upon the outer end of the brake lever 0 it yet having limited amount of movement, andin so doing will release the leg 5 from the notch 8 and let the shipping lever by its own gravity assume'its full line position.

To increase the eflectiveness of the brake lever, I have covered that portion of it which i contacts with the driving drum with a flexible substance as india-rubber or leather marked (1, the said material being unsupported centrally, thus enabling the soft or yielding Inaterial cl to adapt itself readily to the periphery of the roll. 1.

Having described my invention, What I; claim, and desire to secure by Letters Patent, 1s

1. In a spooling machine, a brake or lifting lever, and a pivoted tipping lever parallel to the brake or lifting lever, combined with a drop rod adapted to tip the tipping lever from its normal into its abnormal position, and a device to act directly upon the tipping lever in its abnormal position and move it to positively actuate said brake lever to check the rotation of the driving drum,substantially as described.

2. In a spooling machine, the shaft 6', its wheel 6, the shell roll, a tipping lever, a vibratory leg on which it is pivoted, a drop wire, and means to engage and move the tipping lever'when moved from its normal into its abnormal position by the falling of a drop wire, combined with a brake or lifting lever acted upon by said leg to lift the shell roll, substantially as described.

3. In a spooling machine, a driving roll, a co-operating rotatable yarn receiver, a lifting lever, and a pivoted tipping lever parallel to the lifting lever; combined with a drop rod adapted in its descent to strike against and tip the tipping lever from its normal into its abnormal position; and adevice to act directly upon the tipping lever in its abnormal position and move it to positively actuate said lifting lever to arrest the winding of the yarn upon the yarn. receiver, substantially as described.

4. The driving roll, combined with the brake lever having a soft or flexible face d unsupported centrally, to thus enable the said face to readily adapt itself to the periphery of the driving-roll, substantially. as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN W. FOSTER.
